DYEING APPARATUS.

' Application filed July 13,

To all whom it may covwem:

Be it known that we, JOHN BRANDWOOD and J osEPH' BRANDWOOD, subjects of the King of Great Britain, residing at Elton, Bury, England, have invented new and useful Improvements in Dyeing Apparatus, of

which the following is a specification.

.This invention relates to improvements in apparatus for dyeing cotton and other fibrous textile materials in the loose state,

that is, before the carding and spinning operations, and more especially to apparatus for feeding such materials to the. dyeing machine, the principal object of the invention being to combine with a dyeing machine,

such, for instance, as that shown and described in our co-pending application Serial No. 169,727, a lap-formin machine in such manner that'the materia is fed directly from the lap-forming machine into the dyeing machine in an even layer of any required thickness without first forming the material into a roll.

A further object of the invention is to ,provide means for driving the lap-forming machine from the dyeing machine, said means including means for'throwing the lap forming machine. out of operation at the will of the operator. I

A further object of the invention is to provide means for expelling air from the material while it is entering the dye bath.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention consists in the novel features of construction and combination of parts which will be more fully described hereinafter and particularly pointed out in the claims.

In the drawings accompanying and forming part of this specification,

igure 1 is a diagrammatic side view illustrating the connections between the dyeing machine and the lap-forming machine whereby the latter is driven from the former;

Fig. 2 is a sectional, side view ofi a portion of the dyein machine, illustrating the means for expelling air from the material as it enters the dye bath; and

Fig. 3 is a fragmenta plan view of the feed rollers of the dyeing machipe, illustrating the means for throwing the lapforming machine into and out of operation.

The same characters of reference designatev the same parts 'in' the diflerent figures of the drawings.

In the operation of the dyeing machine described in our co-pending application above-referred to, the material was first formed into rolls in a lap-forming machine, and, in order that the material may be fed to the conveyor of the dyeing machine in a is usually located at a considerable distance from the dyeing machine, so that the laps, after being formed into rolls, must be transported to the dyeing machine and placed onthe feed table and arranged so as to feed the proper thickness to the dyeing machine con-.

veyor.- These operations necessitate a considerable amount of handling. One of the objects of the present invention is to eliminate the expense of transporting and otherwise handling said rolls, and also the necessity of providing a feed table having bearin for the lap rolls.

eferring to the drawings, 2 designates a dyeing tank, which may be similar to that shown and described in our co-pendingv application above referred to, said tank having a traveling conveyor formed of a pair of endless belts 3 and 4 passing between feed rollers 5 and 6 and beneath a guide roller 7, and so-on, in the manner full described in said co-pending application. 11 the present instance, we have provided an additional pair of rollers 8 and 9, mounted for rotation in suitable bearings carried by the tank, one of said rollers being mounted in stationary bearings, while the other is preferably spring-pressed toward its companion roller as shown at 10 (Fig. 2).

An ordinary well-known form of lapforming machine is illustrated diagrammatically at 11 in Fig. 1. This lap-forming machine, however, instead of forming the material into rolls as heretofore, delivers said material on, to an endless traveling apron 12, one of the rollers 13 on which said apron is mounted being mounted for rotation in the lap-formingmachine at the point where the rollsof material are usually wound, the other apron-supporting roll 14 being mounted for rotation in a bracket 15 secured at each side of the front orfeeding end of the tank, forsupporting the ends of the said roller 14. The roller 14 is geared to a gear 16 secured to theshaft of the feed roller 6 of the dyeing machine, whereby the apron is operated during the rotation .of said shaft.

The entire operation of the lap-forming machine is intended to be controlled from the dyeing machine, and for this purpose we have illustrated herein a shaft 17 mounted for rotation in the lap-forming machine, and which shaft is intended to transmit through suitable gearing all necessary motion to the lap-forming machine. The shaft 17,

p in turn, receives its motion from a chain 18, or other suitable flexible transmission, mounted at one end on a sprocket 19 secured to the shaft 17 and at its opposite end on a sprocket 20 forming a part of a clutch member 21 loosely mounted on a shaft 22, which shaft receives its motion from any suitable source of power by means of a bevel gear 23 secured to its opposite end, and which shaft carries the feed roller 60f the dyeing machine. An axially slidable clutch member 24 is mounted on the shaft 22 adjacent to the clutch member 21 for cooperation therewith in the well-known manner, said slidable clutch member bein keyed to the shaft by means of a spline 25. An operating lever 26 is pivoted to a bracket 27, shown herein as supported on the end of one of the feed rollers, said lever having at one end a bifurcated portion or yoke straddling the slidable clutch member and at its opposite end an operating handle or grip 28. It will thus be seen that when the two clutch members are in engagement the lap-forming machine will be operated whenever the shaft 22 is rotated. Should the material not be fed evenly, however, or if for any other reason it is desired to discontinue the operation of the lapforming machine, the sliding clutch member is slid out of engagement with the clutch member 21 by means of the lever 26, so that the operation of the lap-forming machine will immediately cease until the clutch members are again brought into engagement. In

this manner a continuous layer of material 29 may be formed in the lap-forming machine and fed by means of the apron 12 be tween the rollers 5 and 6 of the dyeing ma menace just at the surface of the liquor and squeeze said material so that as it enters the liquor the air is squeezed therefrom and escapes above the rollers. lit is well known that colors, such as indigo and vat colors which are used for dyeing while in a reduced state are quickly oxidized b the admission of air in the dye vat, an therefore the provision of the rollers 8 and 9 located as shown herein is of considerable advantage in preventing deterioration of the dye liquor.

While we have described in detail the structure herein illustrated, it is to be understood that we do not thereby limit ourselves to the precise features of construction shown, as we .are aware that many mechanical changes may be made therein without departing from the spirit and scope of the invention as set forth in the appended claims.

Having thus described our invention,

g combination, a dyeing machine, a lap-forming machine, means for driving said dyeing machine, means between sald machmes for receiving the laps directly from the lap-' forming machine and delivering them to the dyeing machine, and means for driving said lap-forming machine from said dyeing machme, said driving means including a manually operable clutch for throwing the lapforming machine out of operation during operation of the dyeing machine.

3. A dyeing apparatus, comprisin in combination, a dyeing machine, a laporming machine, an endless apron mounted on said machines for receivin the laps directly from the lap-forming mac inc and delivering them to the dyeing machine, means for driving said dyeing machine, and means for transmitting motion from the dyeing machine to said apron.

d. A dyeing apparatus, comprising, in combination, a dyeing machine, a lapforming machine, an endless a ron mounted on said machines for receiving the laps directly from the lap-forming machine and delivering them to the dyeing machine, means for driving said dyeing machine, means for transmitting motion from the dyeing machine to said a ron, and gearing for driving said lap-forming machine from 11w said dyeing machine.

5. A dyeing apparatus, comprising, in combination, a dyeing machine, a lapforming machine, an endless apron mounted on said machines for receiving the laps 5 directly from the lap-forming machine and delivering them to the dyeing machine, means for driving said dyeing machine,

1 means for transmitting motion from the dyeng machine to said apron, and gearing for driving said lap-forming-machine from said 10 dyeing machine, said gearing including a manually o erated clutch for stopping the operation 0 the lap-forming machine while the dyeing machine continues to operate.

In testimony whereof we have signed our l5 names to this specification.
